2. Click "Withdraw" at the top of the page and select "Using the official bridge". Set the withdrawal token type and amount in the input box, click "Review Withdraw" to confirm, and then click "Initiate Withdraw" to enter your password to pay the fee.

  • Using a third party bridgeyou can enjoy a faster withdrawal speed through a third party bridge which will show the estimated required gas fee on the withdrawal page. However, types of token that can be withdrawn through this option are limited.
  • Using the official bridgeit takes a week to withdraw through the official bridge (i.e. Optimism Gateway). After one week, you need to switch to the ETH wallet and open Optimism Gateway to claim your tokens.

Both of these two options can help you bridge tokens from your Optimism wallet to ETH wallet.
